wrong tmp_path alloc size, not uniq temp file

[plepers]

Hi,

It's a small fix for non windows platforms.
The creation of temp file (awdutil_mktmp) is broken on OSX. tmp_path isn't null terminated, then mkstemp don't work properly.

Hey Pierre

Thanks for contributing to the project. All help is highly appreciated.

The thing is, that i am working on a complete make-over for the awd-sdk.

I am making good progress, and i think i will be able to share the new version quite soon.

This make-over / refactor hardly leaves any line of code untouched. For examples, most string-operations will be handled with std::string now.

For more information about the changes i am doing, please have a look at this issue

Any comments on this issue are highly appreciated.

Thanks

Robin

PS: i will merge your pull requests, but they will be overwritten once i commit the refactored library.
